So I'm pretty sure I've already introduce myself, just got really busy and don't know how far back nor have I looked, when I joined I had a 92 240sx withe a swapped in ka24de, after less than 300 miles that engine started leaking oil from seemingly everywhere and then knocking, so a friend had a 92 180sx jdm sr20de(no turbo) that he'd planned on putting in his 89 hatch but it got totaled, so we are putting it in mine, and let me tell you, if you're putting in an sr20, GET A TURBOED ONE! The stock sr20de headers don't fit past the steering column(haven't checked to see if that's common knowledge yet) but my ka headers fit, but the bolt pattern is off, so were cutting the flanges off the sr headers and wielding them to the ka header, the holes line up, just not the bolts(also don't know if this is common knowledge) also we've learned that the previous owner had royally screwed the wiring, it had a ka24e wiring harness manginered onto the ka24de engine and wired the s15 headlights poorly, so that's all fixed and everything is cool now with the wiring, now just to finish the headers, plug it all in, fill all the fluids, and hope it starts lol
